Grounding grids (GGs) are essential to guarantee protection to personnel and equipment in the electrical substation. In this context, GGs provide low impedance path to high currents during faults or lightning strikes to ...

The purpose of this paper is to investigate the influence of frequency-dependent soils with variable soil content on the transient voltages at transmission towers. First, a comparative analysis between the impedance of ...

This paper presents a new common grounded (CG) multilevel boost inverter (MI) topology for single-phase grid-tied photovoltaic (PV) applications. The proposed topology has the capability to fully eliminate the leakage ...

Battery energy storage systems (BESSs) have be-come integral parts in photovoltaic (PV) energy systems due to their fluctuated nature. The most common solutions in the literature for hybrid PV-battery systems are based on ...

The response of grounding grids subjected to lightning currents wasassessed following two different approaches: experimental tests andcomputational simulations. The experimental tests comprise the impression of currents ...
